SPECIFICATION forming part of Letters Patent No. 608,76*?dated August 9,1898. Application filed October 30, 1897.' Serial No. 656,886'. (Nomodel.)

To ML whom, it may concern:

Be it known that we, Lo'r'r FREDERICK and GEORGE HUGH DUGAN, citizens ofthe United States, residing at North Summit, in the county of Indianaand State of Pennsylvania,

p readily adjustable to receive the varying sizes of nuts upon whichthey are brought to bear.

The object of our invention is to provide a reliably-efficientconstruction which will readily enable the operator to instantly adjustthe jaws without the necessity of following the guiding-threads upon thepost, and, further, to so simplify the elements forming our improvedWrench that the same'may be very cheaply manufactured.

In the accompanying drawings, Figure 1 is a perspective view of ourimproved wrench provided with the necessary accessories for renderingthe parts cooperative. Fig. 2 is a longitudinal central section ofFig. 1. Fig. 3 is a perspective detail of the movable jaw and sleeveprovided therefor. Fig. 4 is a detailed central section of thejaw-controller. Fig. 5, 6, and 7 are detailed views of theguiding-collar employed upon the end of the controller contiguous to thehandle.

Briefly stated, our invention consists in providing a threaded post forthe movable jaw and a rotatable longitudinally-movable controller forcooperating with said jaws, thus enabling the movable jaw to be readilyplaced in an adjusted position without the necessity of following thethreads upon said post.

The several details of our invention will be for convenience designatedby gures, the same figure being employed throughout the several views.

In carrying out our invention We provide the threaded post or body 1,having integrally formed uponthe outer end thereof the fixed jaw 2,while the opposite end is provided with the stem 3, designed to receivea tubular handled of the usual or anypreferred construction, said handlebeing secured in position by means of the shoulders 5 and thelocking-nut 6, engaging with the threaded stem 7 as clearly shown inFigs. 1 and 2. The post 1 is preferably threaded throughout the greaterpart of lits length, though the section V8 thereof nearest the fixed jaw2 is preferably left plain and may be provided with a square, oblong, orother form of outline, the oblong variety of outline being illustratedin Fig. 1. The movable jaw 9 is provided with an aperture designed tosnugly fit and move upon the section `S and also upon that part of thepost provided with the guiding-ribs 10. The movable edge has integrallyor otherwise secured thereto the guiding-barrel or tubular flange 11,also provided with `an aperture for receiving the post, upon which itmoves with the jaw 9. I

Designed to coperate with the barrel 11 is the controller 12, which isprovided with a bore of sufficient diameter to permit it to turn uponthe post 1, the inner wall of said bore being provided at oppositepoints with .a series of transversely-disposed ribs or guides 13,designed to coperate with the `guidingribs 10, formed upon the post 1.The series of ribs 13 are disposed, as above stated, upon opposite sidesof the internal bore of the controller and are coextensive in lengthwith the length of the guiding-ribs 10, carried by the post, and it`will be apparent that said ribs will coperate simultaneously with theupper and lower series of ribs 10 when the controller is in the properposition, and, further, that all of said ribs will be disconnected fromleach other when the said controller is properly rotated to bring theribs 13 alongside of the flattened wall 121L of the post, thuspermitting the controller to then be freely moved longitudinally uponsaid post `until the movable jaw is brought to the desired position,when by a quarter-rotation of said controller the ribs 13 willloe-brought into engagement with IOO the ribsrlO, and thus lock the jawsecurely in position for coperatin g with the fixed jaw, and thus enablethe nut to be turned.

In Figs. 5, 6, and 7 we have shown a closing or finishing collar 15,which is provided with the stop-pin 16, corresponding in func,- tionwith the stop-pin 17v formed upon the barrel 11, both being designed topositively check the controller 12 when the adjustable stop-pin 18 hasbeen brought into a position to register with one of the apertures 19 or2O formed upon the opposite face of the barrel 11.

The operation of our improved wrench may be stated to be as follows: Thecontroller 12 is rotated until the series of ribs 13 formed thereon arebrought out of engagement with the sex-rations or controlling-ribs 10,when said controller may be freelyT moved longitudinally, andincidentally moving the movable jaw to the desired point upon the post1, when a reverse rotation or partial rotation of the controller 12 willagain bring the series of ribs 13 into engagement with the series ofcontrolling-ribs 10, and thus positively lock the jaw in an adjustedposition. When the controller has been moved to the right or left therequisite distance to enable the adjustable stop 18 to take into one ofthe apertures 19 or 20, the ribs 21 will contact with the stoppins 16and 17, thereby enabling said regulating-stop to positively enter one ofsaid apertures and reliably hold the controller against casual rotationand displacement during the operation of using the wrench. If deemeddesirable, the series of ribs 13 may have their ends beveled orsharpened to more reliably insure their free entrance into engagementwith the series of controlling-ribs 10.

Believing the advantages, constru ction, and. operation of our improvedwrench have been made fully apparent from the foregoing specification,considered in connection with the accompanying drawings, we willdispense with further reference thereto.

I-Iaving thus fully described our invention, what We claim as new, anddesire to secure by Letters Patent, is-

1. In awrenoh, a post having a fixed jaw and partial screw-guides in theopposite edges in combination with a movable jaw having arearwardly-extendin g sleeve provided with an external groove, andacontroller-sleeve having partial threads fitting said guides and athread on its inner end engaging said external groove and means to lockthe parts in position, all arranged as set forth.

2. In a Wrench, a post having a fixed jaw and mutilated screw-threads incombination a movable jaw having a rearwardly-extending tubular flangeprovided with an external groove, and a controller-sleeve having partialthreads fitting said screw-threads and having an interiorly-reduced endprovided with a thread taking into said external groove, and means tolock the parts in position, all arranged asset forth.

3. In a Wrench, the combination with a post having a fixed jaw withmutilated screwthreads, of a movable jaw having a rearwardly extendedtubular flange provided with an external groove, and a controller havingan interiorly-reduced end provided with a thread engaging said externalgroove, and means to lock the same consisting of a recess in the tubularflange and a spring-actuated pin in the controller fitting the recess,all arranged as set forth.

et. In a Wrench, the combination with a post having mutilatedscrew-threads and a fixed jaw, of a movable jaw having arearwardlyextended sleeve, a controller having partial screw-threadstting said mutilated threads, and also having interiorly-reduced ends, aclosing-collar fitting the rear reduced end, said sleeve fitting theforward reduced end, and means to lock the sleeve, the controller andthe closing-collar, all in position, as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
